Purpose: During arthroscopies, bleeding episodes occur as a result of tissue damage. Irrigation systems assist in minimizing these disturbances. The performance of three arthroscopic irrigation systems in clearing bleeding episodes was evaluated objectively. Methods: One surgeon performed 99 shoulder arthroscopies using three irrigation systems: gravity infusion, single roller, and double roller pump. The three irrigation systems groups were matched postoperatively for type of surgery-acromioplasty, SLAP, release, rotator cuff repair and capsule repair, and operation duration. The recorded arthroscopies were analyzed for the presence of bleeding episodes with a special computer program that automatically detects the tinctures of red-colored blood. A least 20% of an arthroscopic image had to be covered with blood to qualify as bleeding episode. Results: The median (min-max) presence of bleeding episodes as a percentage of the operation time was 6.6% (0.0-43.6%) for gravity infusion, 3.7% (0.2-46.4%) for the single roller, and 3.3% (0.0-19.3%) for the double roller pump, respectively. The large variation could be attributed to the occurrence of arterial bleeding episodes during some procedures. No significant differences were found between the irrigation systems. For a subgroup including acromioplasties and releases, significant differences were found in favor of both roller pumps (P < 0.05). Conclusions: Overall, the roller pumps did not outperform gravity infusion. However, from the results, high-risk procedures for bleeding episodes were identified (acromioplasty and release of a frozen shoulder) that can benefit from the use of roller pumps. A clear view is essential to perform an arthroscopic procedure safely and efficiently. Level of evidence: III. © 2011 The Author(s).
